Sony TV (FE-1 Chassis)
Set shuts down shortly after start up with standby led flashing 2, 4 or 5 times
Check / replace chip resistors R543 (47Kohms) and R541, R573 and R575 (all 100Kohms)

2 flashes indicates an over-current error in line stage, & 4 indicates a frame fault. However, quite often, when 4 flashes occur it can still in fact be an over-current error as well as a frame fault. To prove which is the correct fault, measure pin 52 of the micro (IC001) at switch-on, and if this voltage goes high (anything above 0.6v) then it is in fact over-current. If it stays at 0v then the fault is more than likely within frame stage.
